Thousands Across the World Take Part in International Pillow Fight Day!

Saturday was International Pillow Fight Day! Organised by the Urban Playground Movement, the event has been taking place once a year since 2008. The aim of the Urban Playground Movement is to promote active, social, non-commercial events in the hope that they become a part of popular culture.

Saturday’s pillow fights certainly seemed popular, with events in well over 100 cities and towns worldwide, from Shanghai to Sydney, Madrid to Manchester. We’ve gathered some of the best pictures from around the web under the cut — could this be you next year?
